Description

Technical Field

[0001] This invention relates to the field of color sorters, and in particular to a color sorter for the production of golden locust tea. Background Technology

[0002] The chute color sorter is a mainstream sorting equipment widely used in the tea refining and processing industry. It typically employs a three-stage feeding structure: hopper buffer, vibrating feeder for quantitative conveying, and inclined chute for rectification and shaping. This structure can rectify bulk materials into a single-layer uniform curtain of material that passes through an optical detection zone. Combined with an airflow rejection unit, it achieves precise particle-by-particle sorting, boasting advantages such as high processing efficiency and stable operation. Currently, the industry has established a mature operating parameter system with high matching degree for the material characteristics of different tea varieties. As a specialty tea, Jinhuai tea (also known as Huai Mi tea) also commonly uses chute color sorters in its refining and processing, effectively supporting standardized and large-scale production. However, the currently common chute color sorters still have certain shortcomings when color sorting Jinhuai tea: First, Sophora japonica buds are nearly spherical small particles with smooth seed coats. Their movement is primarily characterized by rolling friction, resulting in a friction coefficient far lower than that of traditional sheet-like tea leaves. Furthermore, they exhibit a high elastic recovery coefficient, strong overall flowability, and weak interlocking effect between particles, exhibiting significant differences in physical properties compared to the design benchmark material of existing equipment. In the hopper feeding stage, the feed inlet parameters adapted for low-flowability sheet-like materials easily lead to gushing of the highly flowable Sophora japonica buds, causing significant fluctuations in flow rate with varying material levels within the hopper, making it difficult to maintain a stable feed rate. In the vibration feeding stage, the low-frequency, small-amplitude vibration mode designed for high-internal-friction materials cannot effectively break up the densely packed state of the spherical Sophora japonica bud particles, making it difficult to spread them out into a more compact form. A thin, uniformly thick layer of material is prone to forming localized material clumps and stacking. In the sloping chute rectification stage, the chute inclination angle and surface parameters designed based on sliding friction balance cannot control the rolling acceleration effect of the golden locust tea. The material is in an accelerated state throughout the chute, and the terminal speed when it reaches the detection zone exceeds the optimal speed range for optical imaging. At the same time, spherical particles lack effective lateral constraints and are prone to lateral segregation. The bouncing caused by the feed drop is also difficult to fully attenuate within the chute's travel distance. These problems together lead to uneven material flow velocity, fluctuating material layer thickness, and particle spatial position drift when entering the optical detection zone. Ultimately, this reduces the clarity of optical imaging and the accuracy of airflow rejection, hindering further improvement in the color sorting quality and production stability of the golden locust tea. Summary of the Invention

Two sets of color sorting modules are symmetrically arranged along the length of the chute plate. The two sets of color sorting modules cooperate with each other to sort the material. The color sorting module includes a light inspection box fixedly installed on the frame. A lamp tube, a CCD camera and an air blowing box are fixedly installed inside the light inspection box.

[0008] As a preferred embodiment of the color sorter for the production of golden locust tea according to the present invention, the material spreading assembly includes several guide rods fixedly installed on a support frame, a support plate slidably installed on the outer side of the several guide rods, several guide rails corresponding to the number of vibrating feeders fixedly installed on the side of the support plate near the vibrating feeder, the guide rails being located directly above the vibrating feeder, sliders slidably installed on the outer side of the guide rails, and a connecting plate being installed between several sliders.

[0009] As a preferred embodiment of the color sorter for the production of golden locust tea according to the present invention, wherein: a plurality of long spring telescopic rods corresponding to the number of vibrating feeders are fixedly installed on the connecting plate, an installation plate is fixedly installed on the telescopic end of the long spring telescopic rods, and a plurality of comb teeth are fixedly installed on the installation plate, the comb teeth being used to comb and flatten the material on the vibrating feeder.

[0010] As a preferred embodiment of the color sorter for the production of golden locust tea according to the present invention, the separation and reset assembly includes two long plates fixedly installed on the support frame and symmetrical to each other along the length of the support frame. The long plates have control slots on the side near the comb teeth. A connecting frame is installed on the outer side of the telescopic ends of several long spring telescopic rods. Short spring telescopic rods are fixedly installed at both ends of the connecting frame. The telescopic ends of the two short spring telescopic rods are slidably connected to the corresponding control slots.

[0011] As a preferred embodiment of the color sorter for the production of golden locust tea according to the present invention, the control trough is composed of a feed section and a reset section that are interconnected. The connection between the feed section and the reset section is designed to prevent backflow, and a transition slope is provided in the middle of both the feed section and the reset section.

[0012] As a preferred embodiment of the color sorter for the production of golden locust tea according to the present invention, the swing assembly includes several fixed plates fixedly installed on the support frame, the fixed plates having an N-shaped groove on the side near the vibrating feeder, and several extrusion rods fixedly installed on the connecting plate and slidingly engaging with the corresponding N-shaped groove.

[0013] As a preferred embodiment of the color sorter for the production of golden locust tea according to the present invention, the driving assembly includes a cylinder fixedly mounted on a support frame, a driving frame fixedly mounted on the output end of the cylinder, a plurality of driving rods slidingly penetrating the support frame fixedly mounted on the driving frame, the ends of the plurality of driving rods being fixedly connected to a support plate, a plurality of toothed rods being installed between the driving frame and the support plate, and a gear meshing with the toothed rods being fixedly mounted on the material control component.

[0015] The beneficial effects of the color sorter for the production of golden locust tea according to the present invention: In this application, by synchronously linking the material control component, the material spreading component, the oscillating component, and the separation and reset component with the drive component, the timing of the material flow rate change and the material spreading action is matched. This allows the material control component to reciprocate at a uniform speed with the cylinder, forming a periodic variable flow rate of material feeding with gradual rise and fall. Compared with the constant large flow rate in the prior art, this can reduce the impact and stacking risk of concentrated material falling from the source, and avoid the violent bouncing of highly elastic Sophora japonica flowers due to a large amount of instantaneous material falling. At the same time, compared with the constant small flow rate solution, it ensures the processing volume per unit time, taking into account both processing stability and production efficiency. In addition, the gradual increase in flow rate corresponds exactly to the reverse working stroke of the material spreading component. The closer to the material drop point in the hopper, the thicker the material layer. The wave-shaped reverse combing effect of the comb teeth is enhanced accordingly, which can promptly break up the thickened material pile and automatically match the material spreading requirements at different locations, achieving uniformity of the material layer thickness throughout the trough. The adaptive matching effect between the material drop flow and the combing action is naturally formed, and the flow rate gradually decreases in sync with the return lifting state of the material spreading component. At this time, the material discharge is reduced synchronously without the need for strong combing action. The comb teeth are automatically lifted and detached from the material layer through the separation and reset component, completely avoiding the problem of material backflow and disturbance of the already spread material layer during the return. This ensures both the uniformity of the material spreading and the continuity of material conveying. Attached Figure Description

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1-10 This embodiment provides a color sorter for the production of golden locust tea, including: a frame 1; a feeding module 2 disposed on the frame 1, the feeding module 2 including a plurality of hoppers 24 and a plurality of vibrating feeders 22; and a material curtain homogenization module 3 disposed on the feeding module 2.

[0030] The material equalization module 3 includes: a material control component 35 disposed in the corresponding hopper 24, the material control component 35 being two rotating plates that can rotate around their own axis, the material control component 35 being used to adjust the material flow area to form a slow-rising and slow-falling cyclic feeding; a material spreading component 31 disposed at the corresponding vibrating feeder 22, the material spreading component 31 being used to reciprocate along the length direction of the feeder to comb the material layer; an oscillating component 33, the oscillating component 33 being used to synchronously control the lateral oscillation of the material spreading component 31 when it moves horizontally, so that the comb teeth 317 complete the material spreading in a wave-shaped trajectory; a separation and reset component 32, the separation and reset component 32 being used to control the material spreading component 31 to lift and detach from the material layer when it moves to the end of its stroke, and to maintain the detached state on the return stroke, and to enter the next round of material spreading after reset; and a drive component 34, the drive component 34 being used to synchronously drive the rotation of the material control component 35 and the horizontal movement of the material spreading component 31.

[0031] It should be noted that the material curtain homogenization module 3 achieves synchronous correlation between the material control component 35 and the material spreading component 31 through the drive component 34. Targeting the near-spherical, highly fluid, and highly elastic physical properties of Sophora japonica buds, it replaces the continuous feeding in the existing technology with a gradually changing cycle feeding to avoid material spurting and impact bouncing. At the same time, the wave-shaped reverse combing material spreading combined with the return lifting and detachment working mode ensures the uniformity of the material layer spreading and avoids material disturbance during the return. Finally, a single layer of material with stable thickness is formed on the vibrating feeder 22, providing a stable foundation for subsequent rectification and optical detection by the chute plate 23.

[0032] Reference Figures 1-10 The feeding module 2 also includes a support frame 21 fixedly installed on the frame 1. The hopper 24 and the vibrating feeder 22 are both fixedly installed on the support frame 21. The discharge end of the hopper 24 is aligned with the vibrating feeder 22. A chute plate 23 is fixedly installed on the frame 1.

[0033] Reference Figures 1-10 It also includes a color sorting module 4. Two sets of color sorting modules 4 are symmetrically arranged along the length of the chute plate 23. The two sets of color sorting modules 4 cooperate with each other to sort materials. The color sorting module 4 includes a light inspection box 41 fixedly installed on the frame 1. A lamp tube 42, a CCD camera 43 and an air blowing box 44 are fixedly installed inside the light inspection box 41.

[0034] Reference Figures 1-10 A collection box 5 is fixedly installed on the frame 1. The collection box 5 is located below the color sorting module 4 and is used to collect the color sorted materials.

[0035] It should be noted that multiple hoppers 24 and vibrating feeders 22 are arranged side by side along the width of the support frame 21 to form a multi-channel parallel feeding structure, which can significantly increase the processing capacity per unit time. The discharge end of the hopper 24 is directly above the feed end of the vibrating feeder 22 to ensure that all falling material falls into the vibrating feeder 22. The chute plate 23 is inclined at the discharge end of the vibrating feeder 22, and its inclination angle is adapted to the rolling friction coefficient of the golden locust rice to rectify the evenly spread material flow into a uniform speed material curtain for subsequent color sorting module 4.

[0036] Two sets of color sorting modules 4 are symmetrically arranged on both sides of the chute plate 23 to form a double-sided detection structure, which can simultaneously collect image information from both sides of the Sophora japonica flower, avoiding the missed detection of defects caused by partial occlusion of spherical particles; the lamp tube 42 provides uniform diffused illumination, the CCD camera 43 is aligned with the detection station of the chute plate 23, and the nozzle array of the air blowing box 44 maintains a preset distance from the detection station, which can spray airflow according to the recognition signal of the CCD camera 43 to remove discolored particles and impurities. The working principle of the above-mentioned color sorting module 4 is the prior art, so it will not be described in detail in this application.

[0037] The collection box 5 has an independent finished product collection chamber and a waste material collection chamber, which correspond to the normal material channel and the air blowing rejection channel of the color sorting module 4, respectively.

[0038] Reference Figures 1-10 The material spreading assembly 31 includes several guide rods 311 fixedly installed on the support frame 21. A support plate 312 is slidably installed on the outer side of the several guide rods 311. Several guide rails 313 corresponding to the number of vibrating feeders 22 are fixedly installed on the side of the support plate 312 near the vibrating feeder 22. The guide rails 313 are located directly above the vibrating feeder 22. Sliding blocks 314 are slidably installed on the outer side of the guide rails 313. A connecting plate 318 is installed between several sliding blocks 314.

[0039] Reference Figures 1-10 A number of long spring telescopic rods 315 corresponding to the number of vibrating feeders 22 are fixedly installed on the connecting plate 318. An installation plate 316 is fixedly installed on the telescopic end of the long spring telescopic rod 315. A number of comb teeth 317 are fixedly installed on the installation plate 316. The comb teeth 317 are used to comb and flatten the material on the vibrating feeder 22.

[0040] It should be noted that multiple sets of guide rails 313 and sliders 314 correspond one-to-one with multiple sets of vibrating feeders 22, and are rigidly connected by connecting plates 318 to achieve synchronous lateral movement, ensuring the consistency of material spreading action in each channel.

[0041] The long spring telescopic rod 315 is in a natural state under normal conditions, allowing the comb teeth 317 to contact the material layer with flexible pressure, avoiding rigid compression that could damage the golden locust rice particles. At the same time, the long spring telescopic rod 315 can extend and retract vertically, providing vertical movement allowance for the lifting and resetting of the material spreading assembly 31. The comb teeth 317 are made of food-grade flexible material with rounded ends. The spacing of the comb teeth 317 is adapted to the particle size of the golden locust rice, which can forcibly disperse the material pile during the combing process without damaging the particles.

[0042] Reference Figures 1-10 The drive assembly 34 includes a cylinder 341 fixedly mounted on the support frame 21. A drive frame 342 is fixedly mounted on the output end of the cylinder 341. A plurality of drive rods 343 that slide through the support frame 21 are fixedly mounted on the drive frame 342. The ends of the plurality of drive rods 343 are all fixedly connected to the support plate 312. A plurality of racks 344 are installed between the drive frame 342 and the support plate 312. A gear 345 that meshes with the racks 344 is fixedly mounted on the material control component 35.

[0043] It should be noted that the cylinder 341 is a uniform reciprocating drive. When the output end extends, the drive frame 342 drives the drive rod 343 and the support plate 312 to move. At the same time, the rack 344 moves synchronously with the drive frame 342. The gear 345 meshes with the rack 344, causing the two rotating plates to rotate synchronously, so that the flow area of ​​the hopper 24 outlet gradually increases. When the output end of the cylinder 341 retracts, it drives all components to reset synchronously, the rotating plates reset and rotate synchronously, and the flow area of ​​the outlet gradually decreases, so as to achieve strict timing synchronization between the material flow rate and the material spreading action.

[0044] By employing a gradually increasing and decreasing cyclical flow rate for material feeding, rather than a constant flow rate, and maintaining strict synchronization between the feeding flow rate and the spreading action, the risks of material impact and stacking can be reduced from the outset. If a constant, high flow rate is used, the highly fluid Sophora japonica flowers will quickly accumulate into mounds at the feeder's inlet, and the highly elastic particles will bounce violently upon impact, resulting in a highly disordered material layer. If a constant, low flow rate is used, while easy to spread, the throughput per unit time is too low to meet mass production requirements. Using a gradually increasing and decreasing cyclical flow rate, the material falls and accumulates smoothly, significantly reducing the impact, bouncing, and localized stacking problems caused by concentrated material feeding.

[0045] Secondly, the increasing flow rate corresponds to the working stroke of the spreading component 31: the comb teeth 317 move from the side away from the vibrating feeder 22 to the side closer to the vibrating feeder 22. The closer to the drop point, the greater the discharge flow rate and the thicker the material layer. The wave-shaped reverse combing effect of the comb teeth 317 is simultaneously enhanced, which promptly disperses the thickened material pile and ensures that the material layer thickness is uniform throughout the trough. The decreasing flow rate corresponds to the return lifting of the spreading component 31. At this time, the discharge amount is reduced simultaneously, and there is no need for strong combing. The comb teeth 317 are lifted and detached from the material layer to avoid the return flow of material and disturbance of the already spread material layer, thus balancing the uniformity of spreading and the efficiency of material conveying.

[0046] Furthermore, by using a periodically varying flow rate in conjunction with synchronous material feeding, there will be no overflow due to flow overload, nor will there be material shortage or empty trough due to insufficient flow. Ultimately, a continuous and uniform single-layer material flow is formed at the discharge end of the vibrating feeder 22, providing a stable material foundation for subsequent chute speed rectification and optical inspection, thereby improving the imaging clarity and rejection accuracy of subsequent color sorting from the source.

[0047] Reference Figures 1-10 The swing assembly 33 includes several fixed plates 331 fixedly mounted on the support frame 21. The fixed plates 331 have N-shaped grooves 332 on the side near the vibrating feeder 22. Several extrusion rods 333 that slide in cooperation with the corresponding N-shaped grooves 332 are fixedly mounted on the connecting plate 318.

[0048] It should be noted that the N-shaped groove 332 has a continuous alternating bending structure along the length of the fixed plate 331. When the extrusion rod 333 moves longitudinally with the connecting plate 318, it is guided by the side wall of the N-shaped groove 332, causing the connecting plate 318 and the slider 314 to swing laterally along the guide rail 313. This causes the comb teeth 317 to swing laterally as they move toward the vibrating feeder 22, forming a continuous wave-shaped combing trajectory. The bending amplitude of the N-shaped groove 332 is matched with the spacing between the comb teeth 317 to adapt to the width of the groove of the vibrating feeder 22, ensuring that the lateral swing range of the comb teeth 317 covers the entire groove width, eliminating blind spots in material distribution, and effectively breaking up local material ridges formed by the aggregation of spherical particles of Sophora japonica.

[0049] Reference Figures 1-10 The separation and reset assembly 32 includes two long plates 321 that are fixedly installed on the support frame 21 and are symmetrical to each other along the length of the support frame 21. The long plates 321 have a control groove 322 on the side near the comb teeth 317. A connecting frame 323 is installed on the outer side of the telescopic ends of several long spring telescopic rods 315. Short spring telescopic rods 324 are fixedly installed at both ends of the connecting frame 323. The telescopic ends of the two short spring telescopic rods 324 are slidably connected to the corresponding control grooves 322.

[0050] Reference Figures 1-10The control slot 322 is composed of a feed section 3221 and a reset section 3222 that are interconnected. The connection between the feed section 3221 and the reset section 3222 is designed to prevent backflow, and a transition slope 3223 is provided in the middle of both the feed section 3221 and the reset section 3222.

[0051] It should be noted that the feed section 3221 and reset section 3222 of the control groove 322 have a double-layer groove structure with vertical offset. The feed section 3221 corresponds to the working stroke of the material spreading component 31. The groove height matches the working position of the comb teeth 317. When the short spring telescopic rod 324 slides along the feed section 3221, the long spring telescopic rod 315 remains extended, and the comb teeth 317 are at the working height to comb the material layer normally. The reset section 3222 corresponds to the return stroke of the material spreading component 31. The groove height is higher than that of the feed section 3221. When the short spring telescopic rod 324 slides along the reset section 3222, it drives the long spring telescopic rod 315 to compress through the connecting frame 323, so that the comb teeth 317 are lifted as a whole and detached from the material surface. The two checkpoints are designed as unidirectional slope structures, allowing the short spring telescopic rod 324 to slide cyclically in only one direction: feed section 3221, reset section 3222, and feed section 3221. This prevents misalignment and jamming of the groove during movement and ensures the reliability of the lifting and reset state switching. The transition slope 3223 is used to connect two grooves of different heights, allowing the short spring telescopic rod 324 to smoothly switch grooves at the end of its stroke. The lifting and reset actions can be completed automatically without additional drive components, realizing the unidirectional material laying logic of the material laying component 31 in the working stroke for material application and in the return stroke for lifting and detachment. This completely avoids the problem of the comb teeth 317 causing material to flow back and damage the already evenly laid material layer during the return stroke.

[0052] During use, the output end of cylinder 341 extends out, and through the drive frame 342, it synchronously drives the drive rod 343 and the support plate 312 to move along the guide rod 311 towards the side closer to the hopper 24; synchronously, the rack 344 moves along with the drive frame 342, and through tooth meshing, it drives each gear 345 to rotate, so that the two material control components 35 rotating plates rotate synchronously, the flow area of ​​the discharge port of hopper 24 gradually increases, and the golden locust rice falls continuously to the feed end of the corresponding vibrating feeder 22 below with a slow increase in flow rate.

[0053] Meanwhile, the support plate 312 drives the connecting plate 318, the long spring telescopic rod 315, the mounting plate 316, and the comb teeth 317 to move towards the side closer to the hopper 24 via the guide rail 313 and the slider 314. During the movement, the extrusion rod 333 moves along the N-shaped groove 332 on the fixed plate 331. Under the lateral guidance of the groove wall, the extrusion rod 333 drives the connecting plate 318 and the slider 314 to swing laterally along the guide rail 313, so that the comb teeth 317 generate continuous lateral swing while feeding longitudinally, and comb the material layer on the vibrating feeder 22 in a wave-shaped trajectory, gradually breaking up the falling and accumulated material clumps, and spreading the material into a single layer of uniform thickness. During this stage, the short spring telescopic rods 324 at both ends of the connecting frame 323 slide along the feed section 3221 of the control groove 322, the long spring telescopic rod 315 remains in an extended state, and the comb teeth 317 always maintain the working height to comb the material.

[0054] When the cylinder 341 extends to its maximum stroke, the short spring telescopic rod 324 moves to near the end of the feed section 3221. As the short spring telescopic rod 324 continues to move, it will squeeze the inclined part of the feed section 3221, causing the short spring telescopic rod 324 to rise. This, in turn, drives the long spring telescopic rod 315 to compress through the connecting frame 323, causing the mounting plate 316 and the comb teeth 317 to rise as a whole. The lower end of the comb teeth 317 completely detaches from the golden locust flower material layer, completing the working feed stroke.

[0055] Next, the output end of cylinder 341 retracts backward, and through the drive frame 342, it drives the drive rod 343 and the support plate 312 to return and translate along the guide rod 311 to the side away from the hopper 24. Simultaneously, the rack 344 translates with the drive frame 342, driving the gear 345 to rotate in the opposite direction, so that the two material control components 35 rotating plates rotate and reset synchronously, the flow area of ​​the discharge port of hopper 24 gradually decreases, and the discharge flow rate gradually decreases.

[0056] At the same time, the short spring telescopic rod 324 slides along the reset section 3222 of the control groove 322, and the comb teeth 317 remain in an elevated state throughout the entire process, without contacting the material layer. It moves with the support plate 312 to the return side without touching the material layer, thus avoiding the backflow of material and damage to the already evenly spread material layer. The extrusion rod 333 moves synchronously along the N-shaped groove 332 during the return stroke. Since the comb teeth 317 have been raised and detached from the material surface, the lateral swing will not disturb the material layer.

[0057] When cylinder 341 retracts to its initial position, short spring telescopic rod 324 moves to the end of reset section 3222. At this time, long spring telescopic rod 315 loses its restriction and resets, thereby driving mounting plate 316 and comb teeth 317 to fall and reset, re-entering the working height. At the same time, the two rotating plates of material control component 35 rotate back to a horizontal state where they are joined together, completely closing the discharge port. This completes one full working cycle, and then the next cycle begins.

[0058] During equipment operation, the vibrating feeder 22 continuously vibrates, conveying the evenly spread single-layer material flow to the discharge end at a uniform speed. After being rectified by the chute plate 23, the material forms a stable single-layer material curtain and enters the color sorting module 4. The lamp tubes 42 in the two optical inspection boxes 41 provide illumination, and the CCD camera 43 simultaneously collects image information from both sides of the golden locust tea. After identifying discolored particles and impurities, the air blowing box 44 precisely sprays airflow through the corresponding nozzles, blowing defective particles into the waste channel. Qualified finished products continue to fall along the channel, and finally the finished products and waste materials fall into the independent finished product collection chamber and waste material collection chamber in the collection box 5, respectively, completing the color sorting process of the golden locust tea.
